VALVE STRUCTURE ronwnnniiisrsLLaiioivsf' f Y To all whom itmag/ concern l Be it known aai, WALTER L. Glass, a.

citizen of the UnitedStates, residin' at` Gusta, in the county of yButler and tate Au of ansas, have invented' certain new and useful Improvements `|4in' Valve Structuresfor Well' Installations, of which the follow-V ing is a specification, reference being had therein to the aocompanyingdrawings. j

This invention relates to valve structures for wellinstallationsand especially for deepY wells, such-.as pumping Voil Wells andthe like, and has for .an object to provide a valve organization tor pumping purposes which may be readily and conveniently withdrawn from and inserted into the'casing of a deep welly as an organized structure.

A further object of the invention is to provide an improved type of valve organization which may be insertedinto and withdrawn from a Well casing` of a deep well as such unitary structure, as distinguished from withdrawing the working valve and valve structure at one operation and Vthen withdrawing the standing valve at a second A operation.

A lfurther object of the invention vis vto provide an organization consisting of a standing valve and a working valve so connected that when the standing valve is properly seated ample working space is allowed for thereciprocation of the working valve without in `any way disturbing the standingl valve, but that when the working valve is moved through a greater amplitude of movement than its normal working reciprocation,

it will at the. insertingymovement seat thev standing .valve and at the withdrawing movement withdrawl the standing valve, leaving the casing clear. y

lVith these andother objects in view the invention comprises certain novel parts, elei ments, units, combinations and functions, as shown in the drawing,ltogetherwith mechanical equivalents thereof, as will be hereinat-er more fully described and claimed.

In the drawings: 'l Y y Figure 1 is a longitudinal vertical dia-` metrical sectional view through a casing with the valve organization shown therein 1 in side elevation and inpumping relation;

f Figure 2 is a vertical diametrical sectional view through a casing showing the valve organization partly in side elevation and partly in section and in relation tor/withdrawing n the standing valve by the withdrawal of the Feiss. warmen L qnossonauqusm, gAlWS-As.v`

responding views. l. H .W Y Itis well known that in thevdeep well` pumping installations, asi for instancev pump. ing oil'wells, a casing 10 is employedflitting into the drill-hole and extending downward; Y ly: to-rthebottom of suchho'leo'r into the ,Y

supply-of lu'idftobe pumped. `At vthe bot'-` tom of this'casing a standing valve'11 is seated.` These standing vvalves are Anormally f of'varioustypes but thevalve shown inthe drawing is :ofl the ball type, a ball 12being cup leathers 15 at lits lower end making a tight with the interior of the casing 10 and at its upper end provided with a valve,

here shown as of the ball type, a ball 16 being mounted in a ball cage 17. .To this structure a sucker-rod '18, Vof the usual and ordinary type is mounted A*extending upwardly through the casing to the usual and ordinary i means of imparting reciprocating power thereto. i .fr f

At the lower end the tubing 14 isprovided with a valve seat 19 through which extends a. .r i

rod 20 having an enlargedv -head 21 proportioned to prevent rits passing throughV the oentraljopening ofthe seat 19. This rod 20 is rigidlysecured tothe topv ofthe ball Vcage 13 V.in any approved manner, as vby the screwthread connectionsQQyso that when suiicient Vstress isexerted uponsaid rod 20, the stand-v ing valvev 11 is-lifted, as indicated at Figure 2. vThelength `ofthe rod 20, however, bejtween the head :21 Aandfthefball cage 13is such `as to provide for thenor'mal reciprocation of the working valve, including the tubingV 1/1 and cup' leathers 15 in theordinary pumping operations, so that. during AVsuch pumping operations the standing valve l11 l remains'stationaryf at the bottom of the casing as usual, the rod 20 extending upwardly and'sliding freely through the seat 19, oi-

iio

tering no resistance to the proper ope-ration and functioning of the working valve inthe provided with av plurality of longitudinal grooves or uri'ovvs 23.

to be understood that the invention is in no Way limited to lthisexact number. The functiony of lthese grooves is ofcourse, to permitV of a freer passage'o the 'Huid up- .ivardlypthrough the valve seat, whichy nor mally Yis out of engagement with the head 2l and only surrounding the rod' 20, Wherebv theV grooves add to the carrying capacity ofthe opening lthrough such seat.

v1When Vthe organization has been withdrawn and is to be replaced, it is obvious that thetwo valves Will be inserted together and'forced downwardly into the casing, the bottom of the tubing 14 engaging the top of the ball cage 1,3 When necessary to exert 'force or ramming action upon the standing valve to insure its proper seatingin the bottom of thev casing. By the employment of such an organization the entire structure I In the drawingl three of these -furrows are shown, but it is'V may be removed from the casing at a single operation of the Withdrawal of the suckerrod and may be replaced in like manner at a single operation,.in the usual Well known manner.

What I claim is: v Y

The combination With a Wellcasing of a standing valve located in the bottom of the Well casing and provided With a ball cage,V a Working valve mounted to reciprocate in the casing above thezstanding valve, a spider carried by the 'Working valve andpresenting a Central'opening, a rod rigidly secured to the ball Cage of the standing valvefand eX- tending slidably through the centralopeningof the spider and provided With a head proportioned to engagel the spider, said rod being provided With longitudinal urroyvsin its perimeter.
